/kloc-in the autumn of 0/954, Wang Xuan was admitted to the Department of Mathematical Mechanics in Peking University. In the first two years, I mainly studied basic courses, and a group of famous scholars, such as Shi Cong, Cheng Minde and Ding, laid a solid foundation in mathematics.
From 65438 to 0956, most students with good grades chose mathematics as their major, but Wang Xuan had different ideas. He had a soft spot for computational mathematics, which was still a new subject at that time. He saw that in the national "Twelve-year Scientific Development Vision Plan" formulated in June 1956, the key disciplines in the future include computing technology; I also learned from the newspaper that computers will have a great magical effect on mankind in the future. He believes that a person must link his career and future with the future and destiny of the country, so as to create greater value and make contributions to society. So, Wang Xuan made up his mind and chose the major of computational mathematics.
1954 to 1958 studied computational mathematics in the department of mathematical mechanics in Peking University.
1September, 1958, joined the work, and graduated from the Department of Mathematical Mechanics of Peking University with a university degree in computational mathematics. Professor and Director of Peking University Computer Research Institute, Academician of China Academy of Sciences and China Academy of Engineering. Academician of the Third World Academy of Sciences. Vice President Chinese People's Political Consultative Conference.
1958 ext. 1978, teacher of radio department of Peking University.
1958, Wang Xuan graduated from university, stayed in the radio department as a teaching assistant, presided over the logic design of the electron tube computer and the debugging of the whole machine, and also participated in some circuit design. Has been working in the hardware front line, working 14 hours or more every day. By reading foreign literature, he gradually realized that only by mastering hardware design, program and application at the same time can innovation be produced.
196 1 year, Wang Xuan turned from hardware to software, but he did not give up hardware and engaged in the research on the combination of software and hardware to explore the influence of software on the future computer architecture.
During the period of 1963, Wang Xuan formed the habit of knowing the current situation abroad before doing the project. In order to speed up English reading, he began to practice English listening. After listening for half an hour every day for more than two years, the reaction speed was obviously accelerated. At that time, few science teachers did this, so "listening to enemy TV broadcasts" later became a "crime" of Wang Xuan in the Cultural Revolution, but it played a good role in his understanding of foreign advanced technology and laid a solid English foundation.
1964, Wang Xuan undertook the ALGOL60 compiling system of DJS2 1 which was being designed at that time, and discussed the computer architecture suitable for high-level languages. Because Wang Xuan has practical experience in hardware, it is easy to come up with hardware methods to overcome the bottleneck in program operation. After several years' efforts, the system has been successfully developed and popularized among dozens of users. It became an early high-level language compilation system in China and was listed in the memorabilia of the development history of the computer industry. This knowledge and practice of software and hardware became the decisive factor for Wang Xuan to undertake the development of laser phototypesetting system later.
1In August, 974, China formulated the national key project "Chinese Character Information Processing Project" (referred to as "748 Project"). Peking University started the research of its sub-project "Chinese Character Precision Phototypesetting System" from 1975, and Wang Xuan led this research project as the technical director. After investigating the development direction of international technology, he made a decision in 1976: to directly develop the fourth generation laser phototypesetting system, which is not available abroad, by leaping over the second generation optical mechanical phototypesetting system popular in Japan and the third generation cathode ray tube phototypesetting system popular in Europe and America, and adopting the technological route of leaping development.
From 65438 to 0975, Wang Xuan heard that there was a "748 project" in China, which was the Chinese character information processing system project. The value and difficulty of this project attracted Wang Xuan. Wang Xuan was ill at home at that time, and he devoted himself to research and development without hesitation. In order to understand the present situation and development trend of foreign research, Wang Xuan often drives to China Institute of Science and Technology Information to consult foreign language materials. In order to save 5 cents, he always gets off one stop earlier, and often saves copying fees by hand. At that time, there were five domestic units engaged in the development of Chinese character phototypesetting system, but they all chose analog storage mode.
From 1975, as the chief technology officer, he led the development of China computer Chinese character laser phototypesetting system and later electronic publishing system. At that time, this system was in a leading position at home and abroad, completely transforming the movable type printing used in China for hundreds of years, occupying 99% of the domestic newspaper industry and 90% of the book (black and white) publishing industry, and 80% of the overseas Chinese newspaper market, and entering Japan and South Korea. The research results won the first prize of National Science and Technology Progress Award and the top ten scientific and technological achievements in China twice. Professor Wang Xuan is known as "contemporary Bi Sheng".
During the period from 1975 to 1993 18, I almost gave up all holidays and worked every morning and afternoon, and my body and mind were extremely nervous and tired.
1in the summer of 976, after investigation and study, Wang Xuan decided to adopt digital storage mode, and directly developed the fourth generation laser imagesetter without commercial products abroad, skipping the second generation imagesetter popular in Japan and the third generation imagesetter popular in Europe and America. He used mathematical knowledge and practical experience in software and hardware to invent high-speed information compression technology (the compression ratio reaches 500∶ 1) and high-speed restoration method for high-resolution glyphs, and took the lead in designing a special chip to improve the restoration speed of glyphs, so that the restoration speed of China glyphs reached the leading level of 700 words per second, which was the first time in the world. In the mid-1980s, the West began to adopt the description method of "contour plus parameters" (that is, the technique of prompting information or control information), and Wang Xuan put forward and realized this method eight years earlier, becoming the first person in the world to use this method. This invention became the cornerstone of the laser phototypesetting system of Huaguang and Founder, and won European patents and eight China patents. Wang Xuan became the first person in China to obtain a European patent.
1976 In September, the Ministry of Electronic Industry gave strong support after learning about Wang Xuan's scheme, and officially assigned the task of developing the Chinese character precision phototypesetting system in the "748 Project" to Peking University, and established the Chinese character information processing technology research room in Peking University, with Wang Xuan in charge of the overall design and development of the whole system.
1July 27, 979, with the joint efforts of the cooperative unit * * *, Wang Xuan presided over the successful development of the main project of the Chinese character precision system, and output an octavo newspaper negative from the laser imagesetter. The State Council's Deputy Prime Minister Fang Yi spoke highly of his visit to Peking University. On August 1979, 1 1, Guangming Daily reported on the front page that the research and application of Chinese character information processing technology has made a major breakthrough-the main project of China's self-designed computer laser Chinese character editing and typesetting system has been successfully developed, which caused great repercussions at home and abroad.
1980 On February 22nd, Jiang Zemin, then deputy director of the State Council Import and Export Administration Committee, wrote a four-page personal letter to several vice premiers in the State Council, opposing the introduction of foreign products that are not suitable for China's national conditions and resolutely supporting the R&D work of Peking University and other units.
1September, 98015th, the research group headed by Wang Xuan successfully discharged a sample book of Sword of Wu Mi with laser phototypesetting system, which was the first book discharged by China in the process of bidding farewell to movable type. Fang Yi read the instructions: "This is a gratifying achievement. Printing has changed from the era of fire and lead to the era of computers and lasers. Suggested support. " 125 October, 1980, Deng Xiaoping gave instructions to "support". This year, Wang Xuan was promoted to associate professor.
From 198 1, Wang Xuan devoted himself to the commercialization of research results, making the Chinese laser phototypesetting system a commodity from 1985 and widely popularized in the market.
198 1 In July, the first computer laser Chinese character phototypesetting system (Huaguang I) developed by Wang Xuan passed the ministerial appraisal jointly held by the State Administration of Computer Industry and the Ministry of Education. The appraisal conclusion is that "compared with foreign imagesetters, it is ahead in Chinese character information compression technology, and the laser output accuracy and some software functions have reached the international advanced level".
1983 Peking University established the Institute of Computer Science and Technology on the basis of the former Chinese character information processing technology laboratory, and Wang was elected as the deputy director.
1984 promoted to professor.
At the beginning of 1985, Huaguang ⅱ machine was successfully developed and put into trial operation in Xinhua News Agency. Since then, Huaguang III, IV and Founder 9 1 have come out one after another.
1986, was hired as a doctoral supervisor.
1987, Economic Daily became the first newspaper in China to try Huaguang III. In the following year, the Economic Daily Printing Factory sold all movable types, becoming the first printing factory in the world to completely abolish movable types in China. During 1989, Huaguang Ⅳ machine began to be popularized in the domestic press, publication and printing industry. By the end of this year, all foreign companies that came to China to develop and sell photo typesetting systems had withdrawn from the Chinese mainland market. By 1993, 99% of newspapers and more than 95% of books and periodicals printing houses in China have adopted the domestic system, and the newspaper and printing industry in China has set off a technological revolution of "bidding farewell to lead and fire and welcoming light and electricity".
After 1988, as the main pioneer and technical decision-maker of Founder Group of Peking University, he put forward the development model of high-tech enterprises, actively advocated the combination of technology and market, and embarked on a successful road of combining Industry-University-Research.
1991-1994, Wang Xuan led the scientific research team of Peking University to constantly seize opportunities and lead the market with innovative technologies, which triggered three technological innovations in the newspaper and printing industries. Farewell to the newspaper fax machine, and directly promote the remote version transmission technology based on page description language (199 1 up), which greatly improved the quality and circulation of China newspapers; Say goodbye to the traditional electronic color separator stage and directly develop open desktop publishing (starting from 1992), which triggered a technological innovation of color publishing; Say goodbye to paper and pen, and adopt the integrated solution of editing process management computer (1994 onwards).
199 1, Wang Dangxuan was elected as the director of Peking University Computer Research Institute. The State Key Laboratory of Word Information Processing and the State Engineering Research Center of Electronic Publishing New Technology were established in 199 1 and 1994, respectively. Both directors were elected by Wang. From 1992 to 1994, Wang Xuan was elected at 1992 as an academician of the third Academy of Sciences and a member of the eighth CPPCC.
1993, Wang Xuan volunteered that his creative peak had passed. He decided to withdraw from the front line of scientific research and fully support young people to create more new ideas and new achievements. This year, he pushed three young people to the position of director of the research room at the same time. He also took a notebook with him to record the interests, specialties, comments and progress of each young person in the research institute. Every day, he ponders how to give full play to the potential of each researcher and give them a stage to fully realize their self-worth. Under his training, a group of young scientists who dare to innovate and struggle have come to the forefront of scientific research.
1In July, 1995, Peking University Computer Research Institute and Peking University Founder jointly established Founder Technology Research Institute, and Wang was elected as the president, thus establishing a long-term integrated system of R&D, production, system testing, sales, training and after-sales service, and establishing a high-tech enterprise with "indomitable spirit": "indomitable spirit" means constantly pursuing new breakthroughs in technology, and "foothold" means commercialization. Practice has proved that this is a successful road to Industry-University-Research integration. This year, Wang Xuan was appointed as the chairman of Founder (HK) Co., Ltd. In September, Vice Premier Li Lanqing inspected CCTV and instructed CCTV to cooperate with Founder of Peking University to develop China's own computer animation production system. So Wang Xuan made a decision: take the development of computer animation production system as an opportunity to develop the digital video field and enter the broadcasting industry. Founder successfully went public in Hongkong in February 65438 in the form of red chips, and the technical level of China's newspaper industry jumped to the advanced ranks in the world. Wang Xuan decided to develop the Japanese publishing system, enter the Japanese market, and rely on independent innovation technology to go international.
In May, 1997 Founder Group and Recruit, the second largest magazine company in Japan, held a signing ceremony for the Japanese publishing system of Founder in the Great Hall of the People, which was the first time that China enterprises exported and sold high-tech application software with intellectual property rights and independent brands on a large scale. Since then, Founder Japanese publishing system has entered Japanese newspapers, advertisements and magazines one after another, and the Korean market has also started.
200 1, Wang Xuan won the highest national science and technology award, and in February 2002 1, he won a prize of 5 million yuan. On March 18, 2002, Peking University took out 5 million yuan from the insufficient funds to reward Academician Wang Xuan who won the highest national science and technology award. This award is the first time in the history of universities in China.
On February 3, 2006, 65438+ 165438 died in Beijing at the age of 70.
